I'm working on a transition from Exchange 2003 to 2010 and the availability information is not showing up in scheduling. All mailboxes have been moved, PF have been replicated including Schedule + free/busy. We are ready to remove the Exchange 2003 server and the last step we did was to remove the connecter between 2003 and 2010. The next step is to remove the Exchange 2003 server . Is the 'remove server' task in Exchange 2003 ESM enough, or do I have to actually do an uninstall of 2003.?
Test Email Autoconfiguration, shows no errors, auto-discover seems to be working properly, except for a Cert Warning because the site name is not on the cert. At what point does 2010 begin to use the availability service instead of looking at the legacy FB info.?
